During our little conversation after the talk, he stressed the fact many people aren’t willing to pay for bugfixes in Eclipse. He’d be willing to work on many of them but someone has to pay the bills. I nodded like everyone else. And we talked about Eugene Ostroukhov and his complaint ““Participate in community!” they said…“. And I immediately saw a parallel in my own history. I had a similar, painful experience with Ed Merks a while ago. That was about EMF and how badly it sucks. And that he didn’t listen to me.
I was mad because I was right and he just didn’t get it.
Yesterday, on the train home, I understood.
I’d like to introduce two new categories of programmers. Both are passionate and enthusiastic about software. The difference is that one group is pragmatic and the other idealistic.
Ed and Tom are pragmatics. They think: “Great feature, I like it, how much will it cost?” If it’s too expensive, they don’t get upset. They think about it, mull it around, consider their options. If there just is no viable way to do it, they can accept that. These people get money to write software.
I’m an idealistic programmer. I get money to stop writing software. That is, I get money to stop writing the software in my head and to start writing the software someone else wants. Not getting what I envision drives me up the wall.
Things can get pretty ugly when those two kinds meet. Because both are egoistic and both are right. It would make sense to make all the changes to EMF that I want. For me and probably a few others. It would cause quite a few problems for Ed, though (mostly because he’d get a lot of complaints by those people who are happy right now).
I’m asking for changes because I have problems. I’m not complaining about petty things. I need to bend EMF and SWT more than the API allows. To solve my problems, I just can’t accept the status quo. The API has to move. But my solution would cause problems for many other people.
Right now, I’m writing software which doesn’t have a lot of customers, so a stable, reliable API is not one of my goals. I can change my API at a whim and no one bothers. Eclipse has millions of customers and every change to any API will cause a tremendous amount of pain around the globe. Say 0.1% have a problem now? That would be at least 1’000 people complaining. One happy, 1’000 after your head. At least. How big is the pressure on Ed to make me happy?
So how to win? I think Linux has the best solution that you can get today. Linux has several release streams that strive in parallel. It’s not a bunch of forks, it’s a bunch of branches. People can hand in stuff that really isn’t ready for prime time. It can be incomplete. It can break other APIs. It can be an experiment. It can evolve. In Linux, there is the next tree.
In Eclipse, evolution is hard. You have to get new features and patches past people you don’t know, who have more experience in evolving APIs, little time and little incentive to hurt themselves. API in Eclipse is hard to evolve because IBM pays many of the core developers. If someone wants some obscure API and the Lotus Notes team will have a problem with that, who will win? The bug report (even with a patch) or your next pay check? There are only a few big commercial products on Linux. Eclipse, OTOH, was created to form the basis for commercial products (hence the EPL). Products that have life cycles between five and ten years. Ten years ago, we had Linux 2.2, KDE 1.0 and SuSE 6.3.
For IBM and SAP, the one year release cycle of Eclipse is way too fast. They have to spend a lot of money on developers just to keep up with all the changes going on in Eclipse and this is for things that can’t be sold to customer (i.e. which don’t earn any money).
So I agree with Bjorn Freeman-Benson that Eclipse needs a set of public git repositories and a low-barrier entry to these repositories (which means one-click install for the build system, no IP checking). It should be a playground, a place where ideas can grow. Not all of them will make it into the mainstream but at least, people can solve their problems without hurting too many others.
At the same time, I’m afraid what will happen when this comes true. But then, I’m an idealistic programmer. I believe that time will tell who was right and that we shouldn’t bother too much upfront.
